在石太高速公路沥青路面大修工程中,针对路面重载交通量大、车辙病害严重的特点,为提高路面的抗车辙能力,首次采用GTM法进行沥青路面设计。在施工控制过程中,适当提高了对路面集料的质量技术要求,并严格施工工艺质量控制,采用大吨位胶轮压路机增加压实功,保证了压实密实度达到设计要求。大修竣工通车四年来,路面平整密实,沥青路面车辙病害得到根治。 In the asphalt pavement overhaul project of Shitai Expressway, for the first time, GTM method is adopted to design the asphalt pavement in order to improve the anti-rutting ability of the pavement due to heavy traffic and heavy rutting. During the process of construction control, the technical requirements for the quality of pavement aggregates are properly raised, and the quality control of construction process is strictly controlled. The application of large-tonnage rubber-tyra roller increases the compaction work to ensure compaction compactness meets the design requirements. Overhaul completion of the opening four years ago, the road surface formation and density, rutting the road disease has been radical.
